To perform encoding and decoding without necessity to transmit the sounding detection result from an encoder to a decoder.
According to the detector result of a sounding detector 104, an input voice is outputted to a voice encoding part 102 or voice decoding part 103 by a switching part 101. An input signal is encoded and spectrum information, power information and sound source information are outputted to a multiplexing part 105 by the voice encoding part 102. An input signal is encoded and spectrum information, power information and sound source information are outputted to the multiplexing part 105 by the voice decoding part 103. On the basis of the information of the encoded input signal outputted from the voice encoding part 102 or voice decoding part 103, it is decided by the sounding detector 104 whether the input signal is sounded or not. Then, the result is outputted to the switching part 101 by the sounding detector 104.
